We just got home from a trip with our 2006 Fleetwood Santa Fe popup with World Friendship Co WF-8725-P converter. We have never had an issue until now and all of the AC outlets inside and outside of the trailer quit working. I may have overloaded it by trying to run the AC at the same time as an electric cooking utensil while hooked up to a 3500 watt generator. The circuit tripped on the generator which I reset. When I got home, I plugged the popup into my garage outlet and still nothing is working. I checked and the breakers didn't trip and the fuses by the converter are still fine. The GFI will not reset. I unplugged everything including the fridge from the trailer and the GFI will still not reset. I don't believe the converter is working because when plugged into shore power the battery is also not charging and I don't hear a hum from the converter. I've narrowed it down to either a bad converter, bad GFI, or bad 30 amp to 15 amp adapter but don't know what to do from here short of trial and error through replacing each component. Any thoughts? I have basic mechanical skills but am far from being an electrician although I do have a multimeter. Thanks for any feedback.
